Abstract: In a backhoe that is a construction machine in which a swash plate angle of a variable capacity hydraulic pump driven by an engine is controlled based on a difference between an actual engine speed of the engine and a target engine speed calculated from an accelerator position, the engine is controlled through isochronous control when the actual engine speed of the engine is equal to or higher than a maximum torque engine speed with which a maximum torque of the engine is able to be output, and the engine is controlled through droop control when the actual engine speed of the engine is lower than the maximum torque engine speed with which the maximum torque of the engine is able to be output.

Abstract: The present invention addresses the problem of providing an industrial vehicle in which an industrial device can be reliably prevented from turning in a near direction beyond a restricted position. The solution is an industrial vehicle provided with an industrial device configured so as to be capable of turning about a joint in a near direction or an away direction, and a control device for restricting the turning of the industrial device so that the industrial device does not turn in the near direction beyond a restricted position, wherein the control device is configured such that an offset position is set in the away direction beyond the restricted position, and the control device initiates an action that stops the industrial device from turning in the near direction when the industrial device, which is turning in the near direction, has turned to the offset position.

Abstract: A working vehicle is configured so that interference does not occur even if an attachment is exchanged and so that a reduction in work efficiency caused by the exchange of an attachment is minimized. A backhoe comprises: a working machine body; a working device which is connected to the working machine body, has joints, and allows an attachment to be removably mounted to the front end of the working device; and a control device in which stop positions are set, the stop positions being those at which the working device is stopped in order to avoid the interference of the working device. The control device has connected thereto: a position sensor which detects the position of the working device; an input means by which the stop positions are set in advance and by which the stop positions are adjusted independently of each other; and a screen operation section which allows selection among the stop positions.
